C12-C15 Alkyl Lactate, 1 kg

Why lightweight, fast-absorbing formulas rely on C12-C15 alkyl lactate

C12-C15 Alkyl Lactate is an ester derived from lactic acid combined with medium-chain fatty alcohols, valued in formulation for its exceptionally light, non-greasy skin feel. It belongs to the group of emollients for cosmetics, ingredients responsible for slip, spreadability and the finishing sensation left on skin after application. Unlike heavier oils, this ester leaves virtually no oily film, absorbs quickly and delivers a dry-touch finish, which explains why it is used far beyond small workshops — it is a staple ingredient in large-scale industrial cosmetic manufacturing worldwide.

The primary industrial use of this ingredient spans day creams, lightweight fluids, serums, sun care emulsions, BB and CC creams, and foundation formulas, where a silky non-tacky texture is essential even at high pigment or UV-filter loading. It is also common in antiperspirant deodorants, lip balms and leave-in hair products, where a smooth glide without heaviness is required. Personal care manufacturers frequently choose this ester precisely because it helps carry active ingredients without leaving hair or skin feeling weighed down.

From a formulation standpoint, this alkyl lactate blends easily with silicones, vegetable and mineral oils, waxes and other esters. Paired with Cetiol RFL, it produces a more pronounced silky slip, while combining it with Cetiol CC results in an almost dry, powdery finish favored in summer and sun protection formulas. For gentle cleansing milks and micellar-style emulsions, blending it with Argan Amphoteric Surfactant delivers mild cleansing without stripping the skin barrier.

Typical usage rates range from 3 to 15 percent of the total formula, depending on the desired texture and finished product type. The ingredient should be added to the oil phase during the heating stage, at approximately 60-75 degrees Celsius, together with other lipid components, before combining with the water phase for emulsification. Store the raw material in a tightly sealed container, away from direct sunlight and heat sources, to preserve its properties throughout the stated shelf life.

The 1 kg package size is well suited for small cosmetic studios, contract manufacturers running short batches and R&D labs testing new formulas before scaling up to full production — this quantity is enough for dozens of trial batches of cream or serum without risking spoilage of unused raw material.
